Premium Wholesale Peptides for Sale from an FDA-Inspected Manufacturer

If you are searching for wholesale peptides for sale with verifiable regulatory credentials, you have found the right partner. Chinese Peptide Company (CPC) is not a reseller or a gray-market distributor. We are a licensed CRDMO with a cGMP manufacturing facility in Hangzhou, China, that has successfully completed a U.S. FDA Pre-License Inspection for the commercial production of a complex peptide API . We supply bulk peptides directly to pharmaceutical, biotechnology, and diagnostic companies across the United States and more than 50 other countries.

Whether you need gram-scale research quantities or metric-ton commercial API supply, our team provides the documentation, compliance, and purity your procurement process demands.

About Chinese Peptide Company

Founded in 2001, Chinese Peptide Company is a peptide and oligonucleotide-focused CRDMO headquartered in Hangzhou, China, with international operations based in California, USA. We provide full-cycle services from early-stage discovery through commercial manufacturing. Our facility operates at metric-ton scale and has been inspected by the U.S. FDA, NMPA, TGA, and EMA .

We are a wholly owned subsidiary of Medtide Inc. (HKEX: 03880), a publicly listed company. This corporate structure provides the transparency, accountability, and financial stability that pharmaceutical procurement teams require from a long-term supply partner.

Why Buy Wholesale Peptides from CPC?

FDA-Inspected cGMP Manufacturing

Our Hangzhou facility passed a rigorous U.S. FDA Pre-License Inspection conducted in early 2026 for the commercial manufacture of a fully synthetic long-chain peptide API . This inspection validated our quality systems, equipment, and documentation practices against the highest regulatory standards. When you purchase wholesale peptides for sale from CPC, you are sourcing from a facility that has been audited by the same regulator that oversees your US-based operations.

FDA DMF Filed for Tirzepatide API

In May 2026, CPC successfully completed its Drug Master File (DMF) filing for Tirzepatide API with the U.S. FDA (DMF No. 043979) . Formulation partners in the United States can now reference our DMF data upon authorization when submitting their own regulatory applications. This means faster timelines for your product development and a supply chain anchored in regulatory compliance—not guesswork.

Full Documentation with Every Lot

Every wholesale order ships with a lot-specific Certificate of Analysis. Our certificates include itemized impurity reporting by individual related substance, peptide content assay reported separately from chromatographic purity, and retention times assigned for the main peak . This level of detail is what separates a legitimate GMP supplier from a research-chemical vendor.

Metric-Ton Scale Production Capacity

Our commercial manufacturing infrastructure supports production at metric-ton scale. We serve over 1,000 pharmaceutical and biotechnology clients globally, and our facilities have passed GMP inspections conducted by the U.S. FDA, NMPA, TGA, and EMA . If your project requires consistent, scalable supply of wholesale peptides for sale, we have the capacity to deliver.

Genuine Reviews from the Research Community

CPC Reviews: See What Scientists Say About Our Peptides

Read authentic reviews from researchers and labs. See why they trust Chinese Peptide Company for quality peptides, custom synthesis, and reliable delivery.

“As a post-doc, my entire project was stalled for weeks because the custom peptide from our usual supplier was consistently ‘sticky’ and wouldn’t purify. My PI suggested trying CPC. I was skeptical but desperate. I emailed their support late on a Tuesday. By Wednesday afternoon, their lead chemist had replied with three specific buffer recommendations based on our sequence. We ordered the 25mg peptide. It arrived with a CoA showing >99% purity, and it worked flawlessly in our binding assays on the first try. They didn’t just sell me a product; they solved my problem. That project is now the cornerstone of my first-author paper. CPC restored my faith in suppliers.”

From a Frustrated Post-Doc to a Believer

“Launching a biotech startup means every single variable is a risk—especially your supply chain. We bet our lead diagnostic candidate on CPC’s ability to reliably synthesize a 40-amino acid peptide with a tricky fluorescent tag. We started with a 100mg test batch. The data was perfect. We then scaled to 5 grams for pilot manufacturing. The consistency from the small batch to the large one was incredible; the HPLC traces were virtually identical. Their team handled all the import documentation to our U.S. facility without a single hiccup. In a world of uncertainty, CPC’s reliability has been our constant. They are a true partner in our growth.”

The Startup's Most Reliable Vendor

“I run a university core facility that synthesizes hundreds of peptides a year. Even we get overloaded or encounter sequences that are beyond our current scale. For over three years, CPC has been our go-to overflow and complexity partner. Why? Transparency. When I send them a difficult sequence, they give me a realistic assessment of yield and purity upfront, not a sales pitch. Their pricing is fair, and the peptides always arrive with exhaustive analytical data that meets our stringent internal reporting standards. They operate with the same scientific integrity we demand of ourselves. I recommend them to my colleagues without hesitation.”

A Core Facility Manager's Trusted Partner

“Our team was moving a novel peptide therapeutic into IND-enabling toxicology studies. We needed a 15-gram GMP-grade batch, and the timelines were aggressive. The big-name CMOs quoted us 9 months and a staggering cost. CPC’s project team presented a clear, phase-gated plan to deliver in 5 months for a fraction of the price. They were not the cheapest bidder, but their proposal was the most scientifically sound. They executed flawlessly, providing weekly updates and all required QbD documentation. The material passed every one of our stringent release tests. CPC proved that elite quality and sensible timelines don’t have to come from a Fortune 500 company.”

Sourcing for Pre-Clinical Studies

“I’m a solo principal investigator at a small teaching university. My budget is tight, and my orders are usually just 10-20mg. I’ve felt ignored by larger suppliers before. My first interaction with CPC was different. The sales rep spent 20 minutes on the phone helping me optimize my sequence to reduce synthesis cost without affecting the active site. They treated my small, fundamental science question with as much respect as a large commercial order. The peptide was perfect, and the personal follow-up email to see if it worked meant a lot. They’ve earned not just my repeat business, but my genuine loyalty. In science, it’s refreshing to be valued as a scientist first, and a customer second.”
